Answer:
17.9  m/s
Step-by-step explanation:
Volume of the slick =  0.5 x π r² h--------------------------------- (1)
Where r = radius of slick
            h = thickness of slick, 10⁻⁶m
If 0.5m³ of oil leaked, then the radius of the semicircular slick can be calculated from equation (1)
V  =  0.5 x π r² h
0.5=  0.5 x  π x  r² x 10⁻⁶
r²   =  10⁶/ π
r =     10³/√π
dV/dt =   πrh dr/dt  + 0.5π r² dh/dt----------------------------------- (2)
Asumming the film thickness is constant , equation (2) becomes
dV/dt =   πrh dr/dt-------------------------------- (3)
dV/dt = 0.1m³/day
r=  10³/√π
dr/dt= rate of expansion of the slick
Substituting  into (3);
0.1 =  π x 10³/√π x 10⁻⁶ x dr/dt
dr/dt = 0.1  x 10⁶/ ( π x 10³/√π)
        =  17.9479 m/s
        ≅  17.9  m/s
